Commercial Expanding Security Doors For Heritage Listed Capitol Theatre

The Australian Trellis Door Company (ATDC) has recently completed an installation of its commercial grade expanding security doors to the historic Capitol Theatre at Melbourne’s Swanston Street.

The RMIT owned heritage listed theatre, part of the Capitol House building originally  designed by Walter Burley Griffin and his wide Marion in ornate Chicago-gothic style, has recently undergone a $40million refurbishment. The specifying architect was Melbourne based Six Degrees Architects and the project managers were Hutchinson Builders.

ATDC’s S04 trackless expanding security doors were installed to the bar areas on two different levels of the building. When unlocked and opened these doors fold and stack back to a minimal  storage size of just 12% of the opening width being secured thus making them an attractive option to specifying architects and developers alike. Further information on ATDC’s S04 system can be found at
